Describe the issue: Channels not listing in OpenSearch Alerting Actions

Configuration: when creating monitors, channels are not listing in the actions eventhough i have multiple channels for teams , email and slack exist. Tried all the Monitor Types and Monitor defining method like visual editor , Extraction query editor etc.

when i try to create using dev console api , its is getting created, Problem is with the dashboard UI. Even i am unable to edit the monitor created from api using dashboard as it gives a blank screen

Please help to fix the issue

Hi @pablo

No its not enabled, only explore is enabled. I tried creating one more rule via api mentioning the channel id, this time it allowed me to edit via UI , but the channels are not listing

Hi @pablo - One more update. The alerts are triggering and i am getting notification in my teams and slack channels. seems the issue is with the UI list actions and alert panel.

@Jijo.john, The API is fine. Could you share your opensearch_dashboards.yml?

I used the explore mode, and I had no issues listing my channels.

I created a Monitor and a Slack Channel through UI.
Could you also share your APIs?

@Jijo.john Thank you for sharing the config. I’ve noticed that you’re using data sources.
When I set data_source.enabled:true I was able to reproduce your issue.
Do you use any external data sources?
